UPDATE, 7:45 PM: The Marlins will also receive catcher Jeff Mathis from the Blue Jays, according to Bob Elliott of the Toronto Sun. Elliott also says it’ll be a 12-player swap when all is said and done.

UPDATE, 7:20 PM: Rosenthal notes that the trade is “not yet official” because Major League Baseball has not been given all the details. Trades involving money require approval from the commissioner.

UPDATE, 6:58 PM: ESPN’s Buster Olney reports that Jake Marisnick, a 21-year-old outfield prospect with a .278/.351/.436 career batting line in the minor leagues, will also be joining the Marlins organization.

UPDATE, 6:34 PM: Morosi says Johnson, Buehrle and Reyes are all going to the Blue Jays, along with catcher John Buck and infielder-outfielder Emilio Bonifacio. The firesale of all firesales.

6:13 PM: According to FOX Sports’ Jon Paul Morosi and Ken Rosenthal, the Blue Jays are on the “verge of acquiring” right-handed starter Josh Johnson and left-handed starter Mark Buehrle from the Marlins. Shortstop Jose Reyes may also be heading north. Much, much more to come, obviously.

The Oakland Athletics ballpark saga has dragged on for years and years and years. They’ve considered San Jose, Fremont and at least three locations in Oakland as potential new ballpark sites. The whole process has lasted almost as long as the Braves and Rangers played in their old parks before building new ones.

In the past several months the Athletics’ “stay in Oakland” plan has gained momentum. At one point the club thought it had an agreement to build a new place near Peralta/Laney College in downtown Oakland. There have been hiccups with that, so two other sites — Howard Terminal, favored by city officials — and the current Oakland Coliseum site have remained in play. There are pros and cons to each of these sites, as we have discussed in the past.

One consideration not mentioned before was mentioned by team president David Kaval yesterday: sea level rise due to climate change. From the San Francisco Chronicle:

Kaval mentioned twice that the Howard Terminal site would have to take into account sea-level rise and transportation concerns — and he said there have been conversations with the city and county and the Joint Powers Authority about developing the Coliseum site.

The Howard Terminal/Jack London Square area of Oakland has been identified as susceptible to dramatically increased flooding as a result of projected sea level rise due to climate change. On the other side of the bay both the San Francisco Giants and Golden State Warriors have had to consider sea level rise in their stadium/arena development plans. Now it’s the Athletics’ turn.

Fifteen of Major League Baseball’s 30 teams play in coastal areas and another five of them play near the Great Lakes. While some of our politicians don’t seem terribly concerned about it all, people and organizations who will have skin the game 10, 20 and 50 years from now, like the Oakland Athletics, are taking it into account.
